Lubricator



UNITED STATES PATENT OFFICE.,

DELOS H. BUMPUS, OF EDENBURG, PENNSYLVANIA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 233,323, dated October19, 1880. Application tiled April 7, 1880. (No model.)

To all whom it may concern:

Be it known that 1, DELos H. BUMPUs, of Edenburg, in the county ofClarion and State of Pennsylvania, have invented certain new and usefulImprovements in Oil-Cups or Lubricators; and I do herebyT declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, wlch form a part of thisspecification.

Figure lis a vertical section of an improved oil-cup, taken through 3 3of Fig. 3, exhibiting the oil-discharge shell at its highest positionand in communication with the oil-reservoir, part of the lever foroperating being shown on the left-hand side. Fig. 2 is a verticalsection ot' the same device, exhibiting theIoil-shell at its lowestposition in communication with the lower discharge-bore, (which mayconnect with an engine or pump,) with the lever for operating the sameshown in part on the right-hand side. Fig. 3 is a cross-section takenthrough lines l and 2 of Figs. l and 2, showing the lever in full in oneposition and in dotted lines in another position. Fig. 4 is an elevationot' the stem and the perforations for receiving and discharging thelubricants, also the screw-thread for operating the oil-shell. It alsoshows, in section, the oilshell with its chamber in communication withthe steam-escape pipe.

The object of my invention is to provide a lubricating-oil cup superiorin mode ot' operating to those now used.

My invention consists of a reservoir, A, secured to a stem, B, solid inthe center at C, and hollow at each end at D and D', which hollow endsare provided with perforations d and d. The upper part, D, has also asteamescape pipe, E, which extends upward beyond the mouth of thereservoir A.

On the center O of the stem B is the recessed screw-thread F, extendingabout halt'- way around it, `for the reception of the lug J, which formspart of the handle Ifor operating the shell.

Surrounding the stem B is an oil-shell, G,

for receiving and discharging the oil. Itis provided with stung-boxes gand g' on each end, which are provided with screw-caps h and p madesteam-tight by asbestus or other suitable packing, (shown at i.) Theshell G is movable on the stem B by means ot' the handle I, and the endJ ot1 the handle I, engaging in the screw-thread F, causes the shell torise or fall on the stem B, and thus communication from the chamber G'can at will be secured with the upper or lower part, D or D', ot thestem B. Ihe shell Gis thrown upward in position, as shown in'Fig. 1, tocharge the chamber G' 5 but before arriving at the oil-ports d theconfined steam, it'any, in G' escapes through the steam-escape pipe E,which is lower than the perforations el', and by the time the shell hasreached its extreme height the steam has all escaped, and then theoilruns from the reservoir A through the ports cl into the chamber G'.The handle I is then thrown to its second position, the lug J traversesthe screwthread F, and the shell G is forced down to the secondposition, as shown in Fig. 2. The ports d and steam-pipe E are thusclosed and the ports d' opened, and the lubricant enters the lower bore,D', through the perforations d' and flows out into the engine or pump.With my improved oilcup or lubricator there is no inconvenience ortrouble or loss of time in mode of operation. A simple turn of the leverin one direction throws the shell up for receiving the lubricant, and aturn in the opposite direction throws said chamber down for depositingor discharging the lubricant. 8 5

The operation ot' my device is almost instantaneous, and there is nosplashing ot' oil, as all the confined steam escapes from thesteamescape pipe E, and does not throw out the oil from the reservoir A.

What I claim as new, and desire to secure by Letters Patent, is-

1. An oil-cup or lubricator consisting, essentially, of a movableoil-chamber, which may at will be placed in communication with portsfrom an oil-reservoir, or with ports to the machine to be lubricated,substantially as shown and described.

2. An oil-cup or lubricator consisting of a suitable reservoir connectedby suitable ports IOO to a movable oil-chamber, which, by a single withthe movable shell G, substantially as 1o motion of a handle, will closeone set of ports shown and described. and open another, substantially asshown and In testimony that I claim the foregoing as my own I aix mysignature iu presence ot' described. 5 3. In an oillubrioator, thesteam-escapes E, two witnesses.
